Haptic Feedback: Getting Started With the DRV2605
A beginner tutorial on adding haptic feedback to interactive projects: the difference between ERM and LRA vibration motors, why you need a dedicated driver chip like the DRV2605 instead of driving a motor directly from a GPIO pin, the built-in effect library that ships on the chip, and a first project wiring a haptic response to a button press.
